The OP doesn't fully understand what the definition of Price Gouging really is. FL raising their in house prices on a transfer does not constitute Price Gouging. A FFL transfer is a service performed by the business. Price Gouging pertains to goods or commodities, and is generally applied only to life sustaining items. Contrary to some people's opinions, a gun transfer is not a life sustaining transaction (not yet at least). It is a service provided by a private entity. As such the entity can place whatever value that they believe fit to provide this service. This value can be driven by external competitors, sustainability, overhead, etc.
The term Price Gouging is being over and falsely applied by too many people in the past month. This is business.
